4 How to use the hob burners
Hob burners
Each hob burner is controlled by a
separate gas tap operated by a control
knob (fig. 4.1) which has 3 positions
marked on the control panel, these are:
– Symbol ● : tap closed (burner off)
– Symbol : High (maximum)
– Symbol : Low (minimum)
Push in and turn the knob anti-clockwise
to the selected position.
Lighting of the hob burners
To ignite the burner, the following instructions are to be followed:
1) Lightly press and turn the knob anti-clockwise, and position the knob indicator to the
symbol printed on the control panel (fig. 4.1).
2) Press the knob to operate the electric ignition; or, in the case of a mains failure light the
burner with a match or lighted taper.
3) Adjust the burner according to the setting required.
Low High
To turn the burner off, fully rotate the knob clockwise to the off position: ●.
The maximum setting of the control tap is for boiling, the minimum setting is for slow
cooking and simmering.
All working positions must be choosen between the maximum and minimum setting, never
between the maximum setting and the “OFF” position.
Fig. 4.1
Electric ignition
The sparks generated by the electrodes close to the burners will ignite the choosen
burner. Whenever the lighting of the burners is difficult due to peculiar conditions of
the gas features or supply, it is advised to repeat the ignition with the knob on
“minimum” position.

Correct use of double-ring burner
The flat-bottomed pans are to be placed directly onto the pan-support.
To use the WOK you need to place the proper stand in order to avoid any faulty
operation of the double-ring burner (Fig. 4.3a - 4.3b).
IMPORTANT:
The special grille for wok pans (fig. 4.3b) MUST BE PLACED ONLY over the pan-rest for the
double-ring burner.

Burners Pan diameter
Auxiliary 16 cm
Semi-rapid 16 ÷ 22 cm
Rapid 20 ÷ 24 cm
Double-ring up to 30 cm
do not use pans with concave or convex bases
Fig. 4.2
Choice of burner
The burner must be choosen according to the diameter of the pans and energy required.
Saucepans with handles which are excessively heavy, in relationship to the weight of the
pan, are safer as they are less likely to tip.
Pans which are positioned centrally on burners are more stable than those which are offset.
It is far safer to position the pan handles in such a way that they cannot be accidentally
knocked.
When deep fat frying fill the pan only one third full of oil.
DO NOT cover the pan with a lid and DO NOT leave the pan unattended.
In the unfortunate event of a fire, leave the pan where it is and turn off all controls.
Place a damp cloth or correct fitting lid over the pan to smother the flames.
DO NOT use water on the fire.
Leave the pan to cool for at least 30 minutes.

5 How to use the Fan left oven (main oven)
General features
Attention: the oven door becomes
very hot during operation.
Keep children away.
The heating and cooking in electrical hot
air ovens take place by forced convection.
The two elements which make this
process take place are:
- Circular element 2500 W
- Grill element 2000 W
NOTE:
Upon first use, it is advisable to operate
the oven at the maximum temperature
(thermostat knob on position 250) for 60
minutes in the position (fan oven) and
for another 15 minutes in the position
(grill-thermostat knob on position 200°C),
to eliminate possible traces of grease on
the heating elements.
WARNING:
The door is hot, use the handle.
Operating principles
Heating and cooking in the FAN oven are
obtained in the following ways:
a. by forced convection
A fan sucks in the air contained in the
oven muffle, which sends it through the
circular heating element and then sends
it back through the muffle.
Before the hot air is sucked back again
by the fan to repeat the described
cycle, it envelops the food in the oven,
provoking a complete and rapid cooking.
It is possible to cook several dishes
simultaneously.
b. by radiation
The heat is radiated by the infra red grill
element.
c. by ventilation
The food is defrosted by using the fan
only function without heat.

Fig. 5.1
Fig. 5.2
Function selector knob (Fig. 5.2)
Rotate the knob clockwise to set the oven for one of the following functions.
Thermostat knob (Fig. 5.1)
This only sets the cooking temperature and does not switch the oven on. Rotate clockwise
until the required temperature is reached (from 50 to 250°C).
The light above the temperature selector will illuminate when the oven is swiched on and
turns off when the oven reaches the correct temperature.
The light will cycle on and off during cooking in line with the oven temperature.
OVEN LIGHT
By setting the knob to this position, only the oven light comes on (15 W).
It remains on in all the cooking modes.
DEFROSTING FROZEN FOODS
Only the oven fan comes on. Use with the thermostat knob set to “●” - other positions have
no effect. The food is thawed by ventilation without heating.
Recommended for:
Quick thawing of frozen foods; one kg requires approximately 1 hour.
Thawing times vary according to the quantity and type of food to be thawed.

Cooking advice
STERILIZATION
Sterilization of foods to be conserved, in full and hermetically sealed jars, is done in the
following way:
a. Set the switch to position .
b. Set the thermostat knob to position 185 °C and preheat the oven.
c. Fill the dripping pan with hot water.
d. Set the jars onto the dripping pan making sure they do not touch each other and
the door and set the thermostat knob to position 135 °C.
When sterilization has begun, that is, when the contents of the jars start to bubble,
turn off the oven and let cool.
HOT AIR COOKING
The circular element and fan come on. The heat is dispersed by forced convection and
the temperature can be regulated to between 50° and 250°C via the thermostat knob.
The oven does not require preheating.
Recommended for:
Food which has to be well-cooked outside and soft or rosy inside, for example
lasagne, lamb, roast beef, whole fish etc.
GRILLING
The infrared grill element comes on. The heat is dispersed by radiation.
Set the thermostat knob to between 50° and 200°C.
Always grill with the oven door closed.
For cooking hints, see the chapter “USE OF THE GRILL”.
Recommended for:
Intense grilling, browning, cooking au gratin and toasting etc.
Do not grill for longer than 30 minutes at any one time on full heat (200°C).
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.
